What is a programmable room thermostat?

... an explanation for householders

A programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set 'On' and 'Off' time periods to suit your own lifestyle. A room thermostat works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached.

So, a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select different temperatures in your home at different times of the day (and days of the week) to meet your particular needs.

Turning a programmable room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system, for example, the size of boiler and radiators.

Neither does the setting affect how quickly the room cools down. Turning a programmable room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy.

The way to set and use your programmable room thermostat is to find the lowest temperature settings that you are comfortable with at the different times you have chosen, and then leave it alone to do its job. The best way to do this is to set low temperatures first, say 18^ , and then turn them up by one degree each day until you are comfortable with the temperatures. You won't have to adjust the thermostat further. Any adjustments above these settings will waste energy and cost you more money.

If your heating system is a boiler with radiators, there will usually be only one programmable room thermostat to control the whole house. But you can have different temperatures in individual rooms by installing thermostatic radiator valves (TRVs) on individual radiators. If you don't have TRVs, you should choose a temperature that is reasonable for the whole ho use. If you do have TRVs, you can choose a slightly higher setting to make sure that even the coldest room is comfortable, then prevent any overheating in other rooms by adjusting the TRVs.

The time on the programmer must be correct. Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time.

You may be able to temporarily adjust the heating programme, for example, 'Override', 'Advance' or 'Boost'. These are explained in the manufacturer's instructions.

Programmable room thermostats need a free flow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fires, televisions, wall or table lamps may prevent the thermostat from working properly.

1.0 Basics

1.1 An introduction to your programmable room thermostat

The TP9000 is a programmable thermostat designed to control both your Hot Water and Heating.

Depending on the setting value in the Installer Advanced Programming (option 41) you can have 7-day, 5-2 day or 24 hour programming. A full explanation of these different methods is located on page 10-11.

The thermostat can also be set by you to provide two different programming blocks which can then be assigned to any day of the week, this is referred to as A/B programme operation.

The Heating side of the TP9000 can be set by your installer to provide up to 2, 4 or 6 time and temperature settings each day, whereas the Hot Water can be set to provide 1, 2 or 3 on/off periods each day.

The thermostat also features useful overrides, including a programmable frost setting.

The TP9000 has some advanced features which the installer will set-up if they are required. There are also a number of advanced features which can be set up by you. These advanced settings alter the way that your thermostat operates, some also affect the programming functions and the user overrides. Please read the User Advanced Programming instructions before programming the unit (see page 20).

General Operation

The TP9000 has two distinct display modes - one for Hot Water, one for Central Heating. The currently selected mode is indicated by a bar at the bottom of the LCD screen when in run mode. The right bar is for Heating, the left bar is for Hot Water.

When programming the TP9000 it is important to be aware of which mode is active before beginning programming. To toggle between modes, press the CH/HW button. The display will change and the indicator bar at the bottom will move to reflect which mode is selected. The flame 🔊) and tap (→ symbols are used in conjunction with the LED's to show the current output status (on/off ). The output status is always shown for both Heating and Hot Water regardless of the display mode.

1.2 Preset programmes

Your TP9000 comes ready programmed with a set of operating times and temperatures which suit most people. Please remember that some of the options available will depend on how the installer has set up the unit.

Note: If set up for two on/off events per day, events 3 and 4 are skipped. If set up for one on/off event per day, events 2, 3, 4 & 5 are skipped. In both cases the events are re-numbered.

Customising the display

For the sake of clarity, the instructions assume that the display setting uses a 24 hour clock, °C and that days of the week are shown as text. All of these settings can be personalised after the thermostat has been programmed, see page 16.

1.3 Setting the correct date and time

Your TP9000 incorporates a real time clock with calendar function that automatically changes time in both Spring and Autumn. The time and date is set in the factory for the UK time zone, and does not normally require adjustment. If you live in another time zone refer to “Time zone off set” (option 4) on page 21. However, should it be found necessary to adjust time or date for any other reason refer to the following instructions.

Setting the date

Press and hold and PROG for 3 seconds, to display date in dd/mm/yy format.

The YEAR number will flash, use or V to correct the year.

Use - or + to move to MONTH, then use or V to correct month.

Use - or + to move to DATE in month, then use or V to correct day in month.

If you attempt to select an invalid date the unit software will reject it and apply the nearest valid date. It is recommended that date is set in the order, yy/mm/dd.

Setting the correct time

After setting the date press PROG to display the time. The time display will flash on and off.

Use the + and - buttons to set the correct time (press and hold to change in 10 min. increments).

Setting the correct day

The day of the week is set automatically. Press PROG to return to normal operation (RUN).

To change from Summer to Winter (clocks back)

With clock display showing, press and hold - button until time moves back.

To change from Winter to summer (clocks forward)

With clock display showing, press and hold + button until time moves forward.

2.7 Remote override into and out of thermostat mode

Selected models are available with a feature which allows a telephone activated switch or window contacts to step the unit into or out of thermostat mode.

The required temperature to be maintained when the building is unoccupied, or when windows are open, must first be set up in User Advanced Programming, option 10, (page 21).

To locally override this feature press either both and V together, or press the MODE button.

2.8 Delay start feature

Your thermostat includes an optional delay start feature to hold off the Heating for a time on mild days when the room temperature at the start of an event is close to the programmed value. If you have enabled this function it can be overridden by pressing either or V buttons. To enable this feature, please refer to User Advanced Programming, option 11, (page 22).

When this function is active, the set temperature will flash on the display and an hourglass symbol will be displayed.

2.9 Optimum start control (OSC)

Your thermostat includes an optional optimum start control. This feature allows you to set the time at which you require a room temperature by. The thermostat then calculates how soon before the event time the system must be turned up to ensure that the room is at the temperature by the required time. A full description of this and how to enable it and set it up is given in User Advanced Programming, options 12 & 13, (page 22-23). When this function is active, the set temperature will flash on the display

3.0 Temporary override buttons

Sometimes you may need to change the way you use your Heating temporarily, i.e. due to unusually cold weather. The TP9000 has two convenient overrides which can be selected without affecting the set programme.

The grey buttons next to the radiator and tap symbol is the + HRS button for heating and the BOOST button for the Hot Water.

For Water display mode, pressing this button once, twice or three times when the system is in OFF, AUTO or ALLDAY mode will cause the Hot Waterto remain on for an extra 1, 2 or 3 hours if already on, or will switch the water on for 1, 2 or 3 hours if currently off. BOOST +1, +2 or +3 HRS will be shown in the display.

For Heating display mode, pressing the +HRS button once, twice or three times will extend the current time/temperature period for 1, 2 or 3 hours, but does not operate if the thermostat is in the OFF or FROST PROTECTION mode. +1, +2 or +3 HRS will be shown in the display. Pressing this button for a fourth time will cancel the +HRS BOOST function.

MODE Pressing this button will alternate between setting the unit in OFF (Thermostat), AUTO or ALLDAY modes for HEATING or ON, OFF, AUTO or ALLDAY modes for WATER. In AUTO mode, all programmed events will run,

whereas in ALLDAY mode, only the first and last events will run. If set for two events per day for Heating, or one ON/OFF event for Water then AUTO and ALLDAY modes are the same. The display will show how many events are to run:

Indicates that unit is in ALLDAY or AUTO mode with 2 events per day for 1 On/Off for Hot Water.

Indicates that the unit is in AUTO mode with 4 events per day for heat or 2 ON/OFF for Hot Water.

Indicates that the unit is in AUTO mode with 6 events per day for heat or 3 for Hot Water.

ON Indicates Hot Water is permanently on (Applies to Hot Water only)

OFF

Indicates permanently off for Hot Water or Thermostat mode (see 2.5 on page 16) for Heating

The INFO button is used to display information about either the next programmed event for the currently selected mode (central Heating or Hot Water) to display the outdoor temperature (if outdoor sensor is fitted) and to show the Service Due Date if set. Below is a more detailed explanation of operation:

If no outdoor sensor is fitted:

Pressing the INFO button will display the time of the next event according to the programmed times. The event time shown will include any +HRS or BOOST extensions. If the next event time is shown fl ashing, this represents an approximate time due to Optimum Start, Delayed Start or a timed override being active.

If an outdoor sensor is fitted:

Pressing the INFO button will display the current outdoor temperature, followed by the lowest and highest outdoor temperatures in the last 24 hours.

If Service Due date is set:

Pressing the INFO button will display the date the service is due.

If in holiday mode:

Pressing the INFO button will display the holiday end date.

4.0 User Advanced Programming Options

Important: The thermostat has been set in the factory to suit most situations, however, there are additional optional settings which can improve the comfort, convenience and energy effectiveness of your thermostat. These are set in the User Advanced Programming and Installer Advanced Programming modes.

4.1 To access User Advanced Programming

Setting 0	UK models: this feature should be left at the factory setting of 0.
Setting 1	Central European time models: this feature should be left at the factory setting of +1:00.
-12 Hours +14 HoursRest of World: use and V keys to select offset from Universal time (GMT) for the location in which the thermostat is being installed.

Option 10 - Frost/ thermostat mode setting

This feature allows the default frost/thermostat mode temperature to be set. Press + until Option 10 is displayed, use and V to select required setting.

5-40°C - Factory setting is 5°C, but can be changed to any value between 5-40°C.

Option 11 - Start-up method
Your thermostat can start up the system in three different ways. Press + until Option 11 is displayed, use Λ and V to select required setting.
Setting 0	Normal: Heating is turned up or down at the programmed times.
Setting 1	Optimum start control (OSC) (or Comfort Setting): This allows you to programme the time at which you would like to be up to the required temperature. The thermostat then calculates how soon before the required time the Heating is turned up. This will vary with weather conditions ranging from a maximum of 120 minutes to 0 minutes before the programmed event time. This setting must be used together with option 12 to match the optimiser setting to the building in which it is installed.
Setting 2	Delay start (or Economy Setting): This is an alternative to OSC. Set the event times in the normal way taking into account the time that the building takes to heat on an average day. The thermostat monitors switch on time, actual temperature and wanted temperature and delays the start of the Heating if the actual temperature is close to the programmed temperature.

Option 12 - Optimum start control pre-heat setting (Option 11 set to 1)
Press + until Option 12 is displayed, use and V to select required setting (only active if Option 11 is set to 1).The optimum start control must be adjusted to match the building energy characteristics. Use the and V keys to selected the required pre-heat period. The table below suggests typical settings.If the building fails to reach temperature on time, increase the setting by 15 minute steps each day until the correct setting is found.If the building reaches temperature ahead of time, decrease the setting by 15 minute steps each day until the correct setting is found.
0:15	15 mins, warm air systems, well insulated building.
0:30	30 mins, warm air systems, well insulated building.
0:45	45 mins, warm air system poorly insulated building.

• If the boiler is not serviced before the due date, a visual and audible warning will start each day at noon. The audible warning will last for 1 minute and will be repeated every hour until a button is pressed to cancel it. If cancelled the alarm will recommence the following day at noon.
